a lclaim. (emu- 105);-

This invention relates to new and useful im i provements and structural refinements in emergency hub adapters, morespeciiically, in emer-' gency adapters forrhubsjand wheel axles on trucks, buses and similar vehicles.

formed with further pertures is, adapted to res ceive the studs 8, the purpose of the spacer being The principal object of the invention is to prothe like.

A further-object of the invention is to provide readily installed and an adapter which may be removed.

Another object of the invention is to provide an adapter which is simple in construction and which cannot easily become damaged videan adapter whichmay be applied to the hub "under emergency conditions, such as may result ,from overloading, excessive" torque strain, and

. more fully described.

An additional object of the invention is to provide an adapter which may be conventionally stored and carried in the vehicle, when not in use.

A still further object of the invention is to provide an adapter which will readily lend itself to economical manufacture. v 7

With the above more important objects in view,

and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:.

Figure 1 is a fragmentary cross sectional view, showing the hub and the wheel shaft, and illustrating the invention in situthereon;

Figure 2 is an end view of the invention per se, the same being taken substantially in the direction of the arrow 2 in Figure 1,' and Figure 3 is a fragmentary plan view of an annular spacer used in the invention.

hike characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention embodies in its construction an adapter designated generally by the reference character 5, the same consisting of a substantially tubular body 6, provided at one end thereof with an out-turned marginal rim I.

The rim I is formed with a plurality of apertures 8, these being spaced in accordance with and beingadapted to receive the wheel studs 8, such as are usually provided on the hub ID, for the purpose of securing the wheel ll thereto.

If necessary, an annular spacer I2 is positioned between the wheel and the adjacent face ofthe rim l, as will be clearly apparent from the accompanying drawings. The spacer I2 is, of course,

A diametrically extending strap I9 is welded to the outer surface of the rim II, this strap being provided substantially in the center thereof'with a screw threaded bore 20, adapted to receivean adjusting screw 2|.

In the event that the hub l0 becomes damaged.

\ or the bolts 22 which normally securethe flange I] to the hub become sheared, the adapter 5 may be applied for emergency purposes, as shown in Figure 1. The rim I of the adapter is secured to the hub l0 and the associated wheel ll by'means of the studs. 8, as has already been set forth.

Simultaneously, the lugs I! are engaged with the apertures IS in the flange l'l, whereupon the screw 2! may be tightened against the flange,

in order to eliminate undue play. It will be noted that in this manner, the adapter I will constitute what may be'referred to. as an auxiliary hub, by directly connecting the flange ll of the shaft ll with the .wheel ll. l

The purpose of the spacer i2 is to facilitate the use of the adapter on hubs having different "depths" or distances from the axle flange to the wheel face. j

' It is believed that the advantages and use of the inventionwill be clearly understood from the foregoing disclosure and accordingly. further dB.

scription thereof at this point is considered unnecessary.

While in the foregoing there-has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

, What I claim as my invention is:

In a wheel mounting structure including an axle shaft terminating at the outer end thereof in a bolting flange formed with a plurality of apertures. a hub, a wheel, and a plurality of studs securing said wheel to said hub, an emergency hubadapter comprising a tubular body, an inturned rim at one end and an out-turned rim at the remaining end of said body. said out-turned REFERENCES mm rim being'secured to said hub by said studs, a plurality .of lugs provided on said inturned rim The following references are of record in the and engaging said apertures. and a clamping A me this Patent:

screw provided l'on said body, said clamping screw 5 UNITED TAT PATENTS being engageab e with the outer end of said shaft. Numb Name m 1,412,058 Johnson Apr. 11, 1922
